The sensory and physicochemical properties of three different recipes for apple cream filling were investigated, focusing on their potential to enhance consumer appeal in pastry applications. Two of the recipes incorporate dried apple cubes (AP1, 48% and AP2, 38% w/w, respectively), while the third recipe (PD) features a cube-free formulation with higher quantities of sugar, potato starch, xanthan gum, dextrose, cinnamon and malic acid. The study evaluated the impact of ingredient composition and processing techniques on sensory attributes. The results indicate that AP1 and AP2 resulted in higher moisture, ash and fiber content but lower viscosity, pH values and emulsion stability compared to PD. All samples exhibited pseudoplastic behavior. The AP2 sample exhibited the most hydrophilic behavior. FT-IR spectra have shown three main peaks, i.e., O-H (3300–3320 cm⁻¹), C=O (1640–1730 cm⁻¹) and C-O (1025–1030 cm⁻¹) stretching vibrations. AP1 and AP2 significantly enhanced hardness and cohesion, providing a more engaging sensory experience. PD offers a smoother, creamier texture with lower inhomogeneity compared to AP1 and AP2 samples, making it ideal for consumers who prefer a uniform mouthfeel. This research demonstrates the critical role of formulation choices in tailoring sensory and physicochemical properties of apple cream fillings to meet diverse consumer preferences. Full article

Trans fats are linked to numerous chronic diseases and cellular dysfunction; however, Spain has not implemented effective regulatory measures to restrict their presence in food products. This study addressed these gaps by analyzing trans fat content in commercial pastries sold in Spain and their biological impacts on mesenchymal stem cells, further examining its compliance with international guidelines. Also, a novel and scalable method for extracting fatty acids from pastry samples was developed and applied, enabling precise analysis using gas chromatography alongside sensory property assessments. The findings revealed significant variability in TFA levels across samples. To assess the biological implications of these TFAs, mesenchymal stem cells (MSCs) were cultured to perform dose–response experiments using two selected pastry samples with the highest TFA content. Cellular adhesion, cytotoxicity, and proliferation were evaluated through MTT assays, bright-field, and fluorescence staining using FITC and DAPI markers. Results demonstrated dose-dependent impacts of TFAs on MSC viability, including reduced adhesion and proliferation alongside increased cytotoxicity. This study underlines the need for stricter regulatory frameworks to monitor TFA levels worldwide, including in Spain’s food industry. Additionally, it highlights the potential health risks associated with excessive TFA consumption, particularly concerning cellular health and growth mechanisms, which provide insights into its potential bioaccumulation implications. These findings provide a foundation for further research into dietary guidelines and industrial practices aimed at minimizing TFA exposure while promoting public health safety. Full article

Background/Objectives: Skipping breakfast is increasingly common among adolescents and has been associated with adverse health and academic outcomes. The average prevalence of breakfast skipping among adolescents is around 16%, although worldwide, it varies greatly across studies, ranging from 1.3 to 74.7%. This study aimed to assess the frequency of daily breakfast consumption and explore the factors associated with its omission in a stratified sample of Spanish adolescents. Methods: A cross-sectional study was conducted among 547 third-year secondary school students (aged 14–15) from both urban and rural areas in Castilla-La Mancha. Self-reported questionnaires were used to gather sociodemographic, psychosocial, and lifestyle data, including adherence to the Mediterranean diet (via the Kidmed questionnaire) and breakfast habits during school days. Descriptive, bivariate (Chi-square), and multivariate (binary logistic regression) analyses were conducted separately for boys and girls. Results: Findings showed a high prevalence of breakfast skipping one or more days (33.46%), with a significantly higher rate among girls (43.27%) than among boys (24.42%). Also, girls were more likely than boys to skip breakfast every day (14.18% vs. 6.87%, p < 0.001). In both groups, low adherence to the Mediterranean diet was strongly associated with skipping breakfast, along with higher screen time, shorter sleep duration, and being overweight/obese. Among girls, low olive oil consumption (OR 0.145 (CI 0.03–0.67) p 0.014) and poor Mediterranean diet adherence (OR 0.140 (CI 0.06–0.34) p < 0.001) were significant predictors. For boys, being overweight/obese (OR 2.185 (CI 1.06–4.52) p 0.035), low Mediterranean diet adherence (OR 0.136 (CI 0.06–0.32) p < 0.001), and not eating industrial pastries were associated factors (OR 0.413 (CI 0.20–0.88) p 0.022). Predictive models demonstrated good discriminatory power (AUC = 0.807 for girls; 0.792 for boys). Conclusions: Skipping breakfast is prevalent among adolescents, particularly girls, and is linked to poor dietary patterns and excess weight. These findings underscore the need for gender-specific nutritional interventions to promote regular breakfast consumption and improve dietary habits in adolescents. Full article

Background: The diet of young people in Spain has changed significantly, with a departure from a balanced dietary pattern and a greater intake of processed foods. Such food generates an acidic environment in the mouth, which promotes the multiplication of bacteria capable of causing inflammation and damage to the gums. Aim: This study aimed to determine the association between the frequency of consuming processed foods and periodontal disease, as well as sex differences, in an adolescent population. Methods: A study was conducted on 233 students aged 15 to examine the frequency of food consumption and its correlation with periodontal disease. Differences were determined via a Student’s t-test to compare the means. A chi-square test was used to compare categorical variables. The 95% confidence interval estimate was used in all cases (p < 0.05). Results: It was observed that girls have a higher mean number of healthy sextants than boys (3.26 $\pm$ 0.20 vs. 2.70 ± 0.21; p = 0.029). A statistically significant difference was noted between healthy and affected subjects in the frequency of consumption of packaged milkshakes (p = 0.003), industrial juices (p = 0.009), industrial pastries (p = 0.018), and fruits in syrup (p = 0.022). When segmented by sex, a statistically significant difference was noted in boys between healthy and affected subjects in the frequency of consumption of packaged milkshakes (p = 0.044), salty snacks (p = 0.032), and cold cuts (p = 0.033); in girls, the difference was detected in industrial juices (0.024). Conclusions: The results of this study suggest that adolescent boys are more affected periodontally than girls. In both sexes, the level of consumption of processed foods affects the presence of periodontal disease. Full article

In this study, hydrogenated fat and butter in traditional puff pastry were partially replaced with vegetable oils from seeds to evaluate their impact on the physicochemical and sensory properties of the final product. The incorporation of vegetable oils led to changes in texture, specifically reducing hardness and chewiness. These modifications influenced the sensory perception of texture in some cases. In terms of color, the addition of vegetable oils reduced luminosity in all reformulated samples compared to the control, while parameters a* and b* were affected by the pigments present in the oils. From a nutritional perspective, this reformulation proved beneficial in reducing total fat content (between 7.34% and 17.19%) and, consequently, the energy value. The inclusion of vegetable oils also led to a decrease in saturated fatty acids, particularly in samples where butter was replaced, while the PUFA content increased (for example, 39.04% in puff pastry with chia oil; 43.04% in puff pastry with poppy oil) as well as the bioactive compounds (vitamin E). Moreover, depending on the oil used, the n-6/n-3 ratio increased compared to the control samples. Regarding sensory evaluation, all reformulated samples were well accepted, with scores above 1. However, across all evaluated parameters, the control samples consistently received higher scores. In conclusion, this study highlights the potential of vegetable oils as a viable alternative to replace traditionally used fats known for their negative health effects. Additionally, the utilization of seed oils derived from agri-food waste contributes to sustainability efforts, aligning with the goals of the 2030 Agenda and promoting innovative applications in the food industry.

This study explores the production and valorization of hemp seed cake protein concentrate (HPC) as a functional ingredient to enhance the nutritional quality and sensory attributes of choux pastry products, specifically éclairs. By integrating varied concentrations of HPC (0%, 1%, 5%, 10%, 15%, and 20%) into traditional formulations, the physicochemical properties, proximate composition, amino acid profile, and sensory characteristics of the resulting pastries were assessed. Sensory attributes were assessed using the check-all-that-apply (CATA) method, where a trained panel selected applicable descriptors from a predefined list. Results indicated that the incorporation of HPC significantly increased protein content from 8.23% in the control sample (HPC0%) to 11.32% in the HPC20% formulation and improved moisture retention, leading to greater exterior and interior éclairs volume, increasing from 42.15 cm³ to 51.5 cm³ and from 18.34 cm³ to 38.47 cm³, respectively. Furthermore, sensory evaluation revealed pronounced differences in attributes such as flavor, appearance, and mouthfeel, with optimal sensory profiles noted at 10% HPC inclusion. The amino acid analysis demonstrated a balanced composition, particularly of essential amino acids, emphasizing HPC’s potential as a valuable protein source, with significant contributions from leucine (8.17 g/100 g protein), isoleucine (5.56 g/100 g protein), and phenylalanine (6.31 g/100 g protein), as well as notable levels of immunoactive amino acids such as arginine (10.92 g/100 g protein) and glutamic acid (20.16 g/100 g protein). These findings highlight the significant nutritional benefits of HPC enrichment, supporting the development of healthier bakery products and contributing to sustainable food practices within the industry.

(1) Background: The consumption of ultra-processed foods (UPFs) constitutes a public health problem given their high availability and easy accessibility among children and young people and their influence on the development of non-communicable diseases in the long term. In this context, culture and religion may be modulating factors for the consumption of processed food. The aim of this study is to assess the consumption of UPFs in Spanish schoolchildren living in Melilla (North Africa), together with the possible impact of religion on this. (2) Methods: A cross-sectional study of 590 Christian and Muslim schoolchildren aged 15–17 years was conducted. The NOVA food classification was used to identify UPFs. Associations between religion and daily consumption were identified using risk analysis (Odds Ratio). (3) Results: Muslim schoolchildren had a higher consumption of industrial juices [OR = 2.700, 95%CI = 1.830–4.037], milkshakes [OR = 2.925, 95% = 1.850–4.748], industrial pastries [OR = 2.217, 95% = 1.440–3.510], sweets [OR = 2.197, 95%CI = 1.437–3.541], chocolates [OR = 2.272, 95%CI = 1.482–3.606] and savory snacks [OR = 3.431, 95%CI = 1.844–6.579] compared to that observed among Christians. (4) Conclusions: Both Muslim and Christian schoolchildren had a high consumption of UPFs. Regarding the potential impact of religion on the consumption of UPF, we observed that Muslim schoolchildren consumed three to four times more UPF than Christian schoolchildren. These results show a shift away from a healthy eating pattern, especially among Muslim schoolchildren. Thus, it is necessary to implement nutritional education strategies in order to understand and control the consumption of UPF in adolescents, thereby reducing the occurrence of non-communicable diseases in the long term.

Spoilage fungi are a significant cause of financial loss in the food and beverage industry each year. These fungi thrive in challenging environments characterized by low acidity, low water activity and high sugar content, all of which are common in fruit fillings used in pastry products. Fruit fillings are therefore highly susceptible to fungal spoilage. Fungal growth can cause sensory defects in foods, such as changes in appearance, odor, flavor or texture, and can pose health risks due to the production of mycotoxins by certain mold species. To reduce food loss and waste and extend product shelf-life, it is critical that we prevent fungal spoilage. Synthetic chemicals such as sorbic acid and potassium sorbate are commonly used as preservatives to prevent fungal spoilage. However, with consumer demand for ‘natural’ and ‘chemical-free’ foods, research into clean-label preservative alternatives to replace chemical preservatives has increased. The objectives of this review are (i) to provide an overview of the sources of fungal contamination in fruit filling production systems, from pre-harvest of raw materials to storage of the final product, and to identify key control factors; and (ii) to discuss preservation techniques (both conventional and novel) that can prevent fungal growth and extend the shelf-life of fruit fillings.

This review aims at the current trends in chocolate ganache production and recipe formulation. Ganache is a blend of chocolate, sugars, dairy, and other ingredients commonly used to fill pralines, pastries, etc. In spite of ganache’s popularity in the food industry, a comprehensive review focused on the application of functional substances and ganache processing has not been discussed in the scientific literature. This review addresses the new ways of applying special ingredients, such as vegetable fats and seeds, flavor infusions, oleogels, hemp products, etc., which can be added to the ganache matrix to achieve desirable properties. In particular, the application of sterols and sterol esters as functional substances of oleogels seems to be a very promising method, enhancing the ganache fat profile. The elevated caloric content that is characteristic of ganache can be substantially attenuated through the application of hydrocolloids and/or fruit-based components, thereby offering the potential for caloric reduction without compromising on taste. The various alterations to ganache formulations by the application of natural substances offer a large base for the development of novel ganache variants and relevant food products. Full article

Wheat flour is a common raw material in the food industry; however, Andean grains, such as quinoa and kiwicha, are gaining popularity due to their quality proteins, fiber, and bioactive compounds. A trend has been observed toward the enrichment of products with these Andean flours, with them even being used to develop gluten-free foods. However, evaluating interactions between raw materials during industrial processes can be complicated due to the diversity of inputs. This study focused on evaluating the technofunctional and rheological properties of wheat, quinoa and kiwicha flours using a simple lattice mixture design. Seven treatments were obtained, including pure flours and ternary mixtures. Analyses of particle size distribution, water absorption index, subjective water absorption capacity, soluble material index, swelling power, apparent density and physicochemical properties were performed. Additionally, color analysis, photomicrographs and Raman spectroscopy were carried out. The results indicate significant differences in properties such as particle size, water absorption and rheological properties between the flours and their mixtures. Variations in color and microstructure were observed, while Raman spectroscopy provided information on molecular composition. These findings contribute to the understanding of the behavior of Andean flours in baking and pastry making, facilitating their application in innovative food products. Full article

Background and objectives: Excessive sodium intake is a major public health issue. Despite the large use of sodium-based additives, their contribution to sodium content is unknown. This work aims to study the association between the use of sodium-based additives and the sodium content of foods sold by a market-leading Portuguese food retail company. Methods: White-label pre-packaged foods and fresh products were included in this study. The salt content of pre-packaged foods was supplied by the company and converted to sodium. The sodium content of non-industrially packaged foods was estimated through food composition tables. Foods were categorized based on the World Health Organization sodium benchmarks. The sodium-based additives on the label’s ingredient list were identified according to Regulation (EU) No. 1129/2011 and counted. Non-parametric tests (n > 5) were used to test the median sodium content (mg/100 g) (minimum, maximum) according to the use of sodium-based additives. Results: A rising sodium content was observed from 0 [56.7 mg (0, 39880)] to ≥ 3 additives [520 mg (60, 2080)] (n = 2451, p < 0.001). A total of 12 categories and 13 subcategories were analyzed. The use of sodium-based additives was associated with higher sodium content for the following categories (a) and subcategories (b): Confectionary (a) (p < 0.001), Chocolates/candies (b) (p < 0.001), Savory snacks (a) (p < 0.001), Salted biscuits (b) (p = 0.027), Fresh (a) and Processed meat/fish (a) (p < 0.001), Processed fruit/vegetables/legumes (a) (p < 0.001), Canned vegetables/legumes (b) (p < 0.001), Ices (a) (p = 0.006), Ready meals (a) (p = 0.030), Composite ready meals (b) (p = 0.001), Cookies (b) (p = 0.007), Cakes (b) (p = 0.022). The use of sodium-based additives was associated with lower sodium content for Beverages (a) (p = 0.002), Fish (heat treated) (b) (p = 0.020), and Pastries (b) (p = 0.045). Non-significant differences were observed for 4 categories and 5 subcategories. Discussion: A positive association between the use of sodium-based additives and the sodium content was observed. Inconsistent results were found across categories, suggesting the need for a deeper analysis of the foods included in each category or subcategory. Full article

The lingonberries represent a valuable resource for many sectors of the food industry in a wide variety of both organic and conventional products. In the context of little information on the use of dried and ground lingonberries mixed with flour in bakery processing, this study aimed to evaluate how the use of spelt wheat flour fortified with dried lingonberry powder in the preparation of cookies, muffins, and brioches with different types of dough can improve their nutritional, functional, and sensory properties, and the degree to which the rheological properties of the dough are affected. The results of the proximate composition analysis revealed that the use of fortified flour in the pastries matrix led to a significant increase in mineral content by an average of 9% and a reduction in protein content up to 7% progressively with the concentration of fruit powder in fortified flour, relative to control samples. The phytochemical profile of pastry products led to a statistically significant enhancement by using fortified flour in their manufacturing formula, with results showing increases of 10 times in total flavonoids content, 9.3 times in total phenolic content, up to 2 times in DPPH (1,1-diphenyl-2-picrylhydrazyl) radical inhibition ability, and for FRAP (ferric-reducing antioxidant power), with values of 14.8 times relative to the control in cookies. The rheological behavior highlighted that the mixing of lingonberry powder with spelt flour is suitable for dough prepared with liquid in order to form gluten up to 15% of fruit addition. The best rated from a sensory point of view were muffins prepared from flour fortified with 10% lingonberry powder. The data resulted from this research suggest that the inclusion of lingonberry powder in spelt wheat flour consists of a promising solution to develop innovative pastry products with improved functional properties.

In this work, a comparison between the extracts of dehydrated yerba mate (Ilex paraguariensis) and bio-waste of yerba mate leaves from the Brazilian industry was made. The incorporation of the functional extract as a preservative/functional ingredient in a pastry product (pancakes) was tested. The individual profile of phenolic compounds was determined by HPLC-DAD-ESI/MS, and the bioactive potential was assessed using in vitro assays for antioxidant, anti-inflammatory, antimicrobial, and cytotoxic activities. The yerba mate extracts revealed a high antimicrobial potential against the tested strains and a very promising antioxidant and anti-inflammatory action. Additionally, revealed a cytotoxic capacity for MCF-7, CaCo and AGS tumor cell-lines. In the three types of pancakes, after 3 days of storage, the chemical and nutritional characteristics remain unchanged, proving the preservative efficiency of the extract. This study showed the benefits of the use bio-waste from agro-industrial sector, focusing on sustainable production and the development of circular economy. Full article

Sour cherry pomace filling (SCPF) and commercial sour cherry filling (CSCF) produced on a semi-industrial scale were tested and compared in terms of food safety, chemical composition, bioactivity, quality, sensory properties and thermal stability. Both samples were safe for human consumption, thermally stable and there was a lack of syneresis. SCPF had a significantly higher fiber concentration (3.79 g/100 g) due to higher skin fraction and is considered a “source of fibers”. The higher skin fraction in SCPF also resulted in a higher mineral quantity (Fe—3.83 mg/kg fw) in comparison to CSCF (Fe—2.87 mg/kg fw). Anthocyanins concentration was lower in SCPF (7.58 mg CGE/100 g fw), suggesting that a significant amount of anthocyanins was removed from SC skin during juice extraction. However, there was a lack of statistical differences in antioxidant activity between the two fillings. CSCF was more spreadable, not as firm and less sticky, with lower storage and loss modulus values than SCPF. However, both fillings exhibited acceptable rheological and textural behaviour for fruit fillings. According to the consumer pastry test, 28 participants preferred each pastry; thus, there was a lack of preference toward any of the tested samples. SCP could be used as a raw material for the bakery fruit fillings industry, which leads to the valorization of food industry by-products. Full article
